I am sending a mail from my RHEL Machine and all it response positive:

Code:

[root@build ~]# echo "Hello" | mail -v -s "hi" ar2@ient.com
ar2@ient.com... Connecting to [127.0.0.1] via relay...
220 build.ient.com ESMTP Sendmail 8.13.1/8.13.1; Thu, 26 Nov 2009 15:10:09 +0530

any idea how gonna I troubleshoot?
It is using relay.
Is there any tool I can trace out where the mail is stucking.

Hi,

The mail is not accepted by lonhub1.ient.com. [10.225.55.18] for some reason.
Maybe you can find the reason in the dsn sent back to you, or in the logs of lonhub1.ient.com if you have access to them.
Else try to telnet directly to lonhub1.ient.com on port 25 and see if you can send an email using the same from: and to: addresses.

Regards

Ohh..Got the Solution..
the DS Entry in sendmail.cf was going missing.
Added the Relay hostname and now its working ;>
